Claims

[Scope of utility model registration request]

A fixed piece fixed in the case, a movable piece whose base end is attached to the case and makes and breaks the contact between the fixed piece, a weight attached to the tip of the movable piece, and a weight attached to the tip of the movable piece; a coil spring having one end locked and the other end attached to the case to support the weight and allow vibration of the weight;
A vibration detector characterized in that the contact is composed of two contact parts respectively connected to two circuits, and each of these two circuits is provided with a display means for displaying connection/disconnection of each contact part.
